自然通风条件下室内外脉动风的相关性研究

Study on Correlation between Indoor and Outdoor Pulsation Wind under Natural Ventilation

为研究建筑自然通风设计用气象参数,需研究建筑室内外脉动风特性的相关性。本文针对深圳市某办公大楼室内外空气流动的特性进行了实测和分析,得出如下结论:自然通风情况下,建筑室内外的风特性参数高度相关的有平均风速、湍流强度与脉动风频,并且三个参数均呈现出正相关的关系,即室内的平均风速值、湍流强度与脉动风频取决于室外的对应参数。

For the research on meteorological parameters of the natural ventilation design of architectures, research on correlation of indoor and outdoor pulsation characteristics is necessary. This thesis is based on actual measurement and analysis of indoor and outdoor air movement characteristics of an office building in Shenzhen. Conclusions are as follows： average wind speed, turbulence intensity, and pulsation wind frequence are the most related factors of indoor and outdoor air movement characteristics, and they are all positively related, that is average wind speed in door, turbulence intensity, and pulsation wind fre- quence, which depend on outdoor corresponding parameter.
